Tóm tắt nội dung

This paper presents a new architecture of electric power network for smart building, namely Three-wire Network. The aim of the proposed network is to satisfy the increasingly quality and reliability requirement of power supply, accommodate the on-site renewable energy source, at the same time increase the overall energy efficiency. The paper is then determining the optimal planning of the proposed network: the capacity of the onsite power sources, power converters and energy storage devices, etc. to minimize the total cost during its lifetime. The cost including capital cost, operation and maintenance cost and fuel cost, etc. that occurs at different time is equivalently converted back to the initial stage by an interest rate to form the objective function, called Net Present Cost. The proposed network and formulation is then applied in an illustrative example to show the optimal configuration of Three-wire Network according to the estimation of the electric demand and market price.
